Dataset
my-patents-data
Two Parquet files hold global patent publication records paired with quality indicators for Chinese invention patent families from 2003 to 2019, with each row representing a focal family and carrying cumulative measures such as semantic knowledge recombination, strict historical semantic novelty, and IPC-based robustness.

Dataset card
The my-patents-data repository, published on Hugging Face by user niban73, merges a global invention-patent publication table with Chinese patent-family quality measures covering 2003–2019. It is distributed as two Parquet files with no explicit license.
What this dataset contains
Each row corresponds to a Chinese focal invention patent family from 2003 to 2019, with the publication table joined to a quality master table via a `family_id` key. The focal-family quality table is expected to contain roughly 121,309,581 rows, while the joined publication table is expected at about 10,790,043 rows. The repository is flagged as private on the platform, and the publisher advises reviewers to confirm source-data license and redistribution rights before making it public.
Structure and fields
No column schema is exposed in the metadata, so specific field names beyond the join key `family_id` cannot be confirmed from the facts provided. The publisher notes that family-level quality measures such as KI, CD, and GFT may contain missing values rather than being zero-filled, and that PageRank values of zero may reflect families outside the identifiable citation graph. Two Parquet files appear to represent the global publication table and the focal-family quality table respectively.
How analysts use it
Because the repository is marked private and the license is unstated, downstream redistribution is restricted until terms are clarified. For investment funds focused on Chinese innovation and intellectual property, the dataset could plausibly support benchmarking listed companies by patent quality or tracking innovation intensity across sectors, but any such use requires verifying the source-data license and redistribution rights first.
